How do you track trends in Tableau when there is a high degree of fluctuation in our data? Try using a moving average!
A moving average is an average of a collection of points around a specified point. For each mark in our view, Tableau will calculate the average of the mark's value and the value of several previous marks. This creates an average value that "moves" over time.
Our fluctuations can be smoothed out to some degree, giving us a clearer explanation of the trends in our data over time.
